TI  - Comprehensive Assessment of the Left Ventricular Systolic Function in the Elderly 
      with Acute Myocardial Infarction Using Echocardiography.

AB  - AIM: To evaluate the left ventricular (LV) systolic function in elderly with 
      non-ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial 
      infarction (STEMI) using real-time three-dimensional echocardiography (RT-3DE) 
      and two-dimensional speckle tracking imaging (STI). METHODS: Forty NSTEMI and 
      forty STEMI patients after undergoing percutaneous coronary artery intervention 
      (PCI) were enrolled. The myocardial segments were supplied by the infarct-related 
      artery (Myo-(IRA)) which were indicated by the selective coronary arteriography 
      (SCA). The LV end-diastolic volume (LVEDV), end-systolic volume (LVESV), stroke 
      volume (LVSV) and ejection fraction (LVEF) were acquired by 4D LV Volume Tom Tec. 
      LV longitudinal peak systolic strain (LPSS), radial peak systolic strain (RPSS), 
      circumferential peak systolic strain (CPSS) of Myo-(IRA) segments, LV rotational 
      peak degree in the base (rot-(base)) and in the apex (rot-(apex)), and twist were 
      acquired by strain analysis software. Forty older healthy individuals were 
      included as normal controls. RESULTS: The LVEF of the NSTEMI and STEMI patients 
      at 1 week after PCI were significantly lower (P<0.05), then, this parameter was 
      improved in both groups after 3 months, but was still significantly lower than 
      that of the controls (P<0.05). The LPSS, RPSS, CPSS of the Myo(-IRA) segments, 
      rot(-Base), rot(-Apex) and twist in both groups were significantly lower than 
      those in the controls. The LPSS and CPSS of the Myo-IRA segments, rot(-Base), 
      rot(-Apex) and twist in NSTEMI patients were obviously higher than those in STEMI 
      patients in 1 week and 3 months after PCI (P<0.05). After 3 months, the RPSS of 
      NSTEMI patients was improved notably and was obviously higher than that of STEMI 
      patients (P<0.05). All these values in STEMI and NSTEMI patients were improved 
      after 3 months, apart from LPSS in STEMI patients (P>0.05), but were still 
      significantly lower than those in the controls (P<0.05). CONCLUSION: RT-3DE and 
      STI can sensitively assess LV systolic function with different extents of 
      transmural damage.
